Here you can read about The KISS Amp 300B, a project by Andre Jute to explain the design and construction of a single ended, zero negative feedback, triode vacuum tube ultra-fi amplifier to those who have not built one before.

The KISS Amp INDEX
Make sure you have the latest KISS 100 file by the date above. This page will build up to the contents list, introduction and so on of The KISS Amp.
For the time being it is a place to put a rolling contents list and announcements about illustrations.
The main project papers and illustrations are accessible through the fiultra netsite at:

The fiultra site is the only place the schematics of the amplifiers under consideration will be published. It is likely that not all the files and illustrations will be on fiultra all the time, so download what you want to keep. There is discussion of The KISS Amp on the newsgroup rec.audio.tubes. Note that versions of the files on the newsgroup may show corrupted text or formulae. No guarantees are given but we try to do better with the files posted at fiultra. All these texts and illustrations are copyright (c) Andre Jute, not for commercial use or publication other than as indicated.
